61 * XmuConvertStringToBitmap:
62 *
63 * creates a depth-1 Pixmap suitable for window manager icons.
64 * "string" represents a bitmap(1) filename which may be absolute,
65 * or relative to the global resource bitmapFilePath, class
66 * BitmapFilePath.  If the resource is not defined, the default
67 * value is the build symbol BITMAPDIR.
68 *
69 * shares lots of code with XmuConvertStringToCursor.
70 *
71 * To use, include the following in your ClassInitialize procedure:
72
73static XtConvertArgRec screenConvertArg[] = {
74    {XtBaseOffset, (XtPointer) XtOffset(Widget, core.screen), sizeof(Screen *)}
75};
76
77    XtAddConverter("String", "Bitmap", XmuCvtStringToBitmap,
